Solution Overview
Problem
Lightweight camera equipment struggles to replicate the smooth movements achieved with heavier systems, as the reduced mass makes it difficult to maintain smooth panning, tilting, or rolling.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If heavy equipment is used, then smooth movements are achieved, but portability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical inertia-based smooth movement systems with an electromechanical system using PCB stator motors. These motors use electromagnetic fields to generate motion, eliminating the need for heavy mechanical components while maintaining smooth pan, tilt, and roll movements through electronic control of motor torque and speed.
Solution Approach 2:
The patent changes the physical parameters of the motor system by using PCB-stator construction with integrated circuitry. This allows precise control of motor output parameters (torque, speed, acceleration) to replicate the movement characteristics of heavy equipment without requiring actual heavy mass, thereby achieving smooth movements with lightweight components.
2Weight of moving object
If lightweight equipment is used, then portability is improved, but smooth movements deteriorate
Solution Approach 1:
The patent substitutes mechanical inertia with electromagnetic force control. The PCB stator motors can generate controlled electromagnetic torque to produce smooth movements without relying on heavy mechanical mass, allowing lightweight equipment to achieve the same movement quality as traditional heavy systems.
Solution Approach 2:
The patent implements dynamic control of motor parameters through integrated circuitry on the PCB stator. This allows real-time adjustment of motor characteristics (torque, speed, acceleration profiles) to optimize movement smoothness, enabling lightweight equipment to dynamically compensate for its lower mass and achieve stable, smooth operation.
3Ease of operation
If traditional friction adjustment systems are used, then operational control is achieved, but adaptability to different physical properties deteriorates
Solution Approach 1:
The patent replaces static friction adjustment mechanisms with dynamic electronic control of motor parameters. The PCB stator motors can electronically adjust torque, speed, and acceleration characteristics to adapt to different payloads and operational requirements, providing both ease of operation and high adaptability that mechanical friction systems cannot achieve.
Solution Approach 2:
The patent enables changeable physical properties through electronic parameter control of the motors. The integrated circuitry on the PCB stator allows programmable adjustment of motor characteristics to mimic different mechanical system behaviors, providing adaptability to various physical properties while maintaining simple operational control through electronic interfaces.

AI summary
Camera heads having up to three axes of rotation (e.g., pan, tilt, roll). Each axis of rotation coincides with the rotational output of a PCB stator motor. PCB stator motors are used to prevent cogging and to reduce weight, while giving haptic feedback to a user that allows the camera head to mimic the physical properties of various mechanical camera heads. For example, despite being lightweight, an embodiment of the inventive subject matter can imitate the feel of a much heavier mechanical system.
